JULIUS J. KARGES, OF JACKSON COUNTY, MISSOURI.

FRICTIONAL GLAMPING DEVTCE.

To all whom it may concern:

Be it known that I, JULIUs J. KARGES, a citizen of the United States,residing in Jackson county, in the State of Missourl, have invented acertain new and useful Improvement in Frictional Clamping Devices, ofwhich the following is a specification.

My invention relates to improvements in frictional clamping devices.

It is particularly adapted for use in connection with display standswhich employ sliding members for supporting goods to be displayed. I

My invention provides further a novel d1splay stand which may be readilyadjusted to suit the purposes for which it may be employed, which ischeap to manufacture, 1s light in weight, which is durable and whlch isnot liable to get out of order.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawing which illustrates the preferred embodimentof my invention, Figure 1 is a perspective view of my improved displaystand provided with two of my improved frictional clamping devlces. Fig.2 is a side elevation of one of my improved clamping devices detachedfrom the stand. Fig. 3 is a view similar to Fig. 2 showing a rod heldclamped between the members of my improved clamping device. Fig. 4 is anenlarged longitudinal vertical sectional view of an end portion of myimproved clamping device.

Similar reference characters designate v similar parts in the differentviews.

1 designates the base of the display stand, 2 a tubular standard securedto and extending upwardly therefrom, 3 a vertical stem slidable in thestandard 2, and having a lateral arm 4 secured to one side of arectangular wire frame 5 which is horizontally disposed.

Mounted on the frame 5 are one or more of my improved clamping devices,each comprising two resilient members, preferably consisting of two flatspring bars, of steel or other suitable material, designatedrespectively by 6 and 7. The end portions of the bar 6 are reverselybent to form inwardly extending arms 8, disposed on the same'side of thebar 6 and provided respectively with means slidablyengaging the adjacentends respectively of the bar 7. Such means preferably consists of twopins 9 which extend through holes provided therefor in the bar 6Specification of Letters Patent. Patented Ma a "7 1 916 Applicationfiled June so, 1915. I

and through holes provided therefor in the arms 8 respectively. I Thebar 7 near its ends 1s provlded with two holes through which the pins 9respectively extend.

The ends of the bar 7 are disposed between the bar 6 and the arms 8 andare respectively adapted to be .moved longitudinally relatively to saidpins.

The inner ends of the arms 8 normally bear against the adjacent side ofthe bar 7, the latter being bow shaped and having its convex sidebearing, adjacent to the middle of the bar, against the adjacent side ofthe bar 6, which is, preferably, also bow shaped.

and has its convex side against the bar 7, as shown in Fig. 2.

As shown in the drawing, the bar 7 adacent to its ends, and adjacent towhere it bears against the ends of the arms 8, is bent toward the bar 6.

By means of the construction just described, when a wire or rod of theproper diameter is inserted transversely, as the rod or wire, 10 in Fig.3, it may be slid between the bars 6 and 7 from one'pin 9 to the otherpin 9, and at all points between said pins will be held clamped by thebars 6 and 7 with substantially the same spring pres. sure. This permitsthe clamping device to be slippedonto the frame 5, as shown in Fig. l,and to firmly clamp said frame in any position thereon to whichtheclamping device may be adjusted longitudinally or laterally. At the sametime the yielding clamping pressure permits of the easy and quickadjustment of the clamping device to the position desired.

By providing two clamping devices mounted on the frame 5, as shown inFig. 1, they may serve as two oppositely extending arms for supportingthe goods to be displayed. V

The arms 8 are preferably inclined toward their ends and toward the bodyof the member 6, and their ends bear upon the member 7 at points 11,respectively at substantial distances from the ends of the member 7, sothat too great a pressure will not be exerted against the rod or wire 10when it is forced past said points 11 topositions adjacent to the pins9. The end portions of the member 7 are preferably inclined from saidpoints 11 toward their ends and toward the body of the member 6 so thatsuch end portions may exert sufficient pressure upon the rod or wire 10.

WVith the construction described, the rod or wire 10 or the frame 5 willbe clamped by a substantially uniform pressure in any po sition to whichit may be adjusted.

While I have shown the pins 9 as employed for attaching the members 6and 7 together, other suitable means may be employed.

I have shown the clamping device as forming a part of a display stand,but it is obvious that it may be put to many other uses where it isdesired to obtain a uniform sliding clamping engagement of the devicewith another article.

I do not limit my invention to the structure shown and described, asmodifications, within the scope of the appended claims, may be madewithout departing from the spirit of my invention.

WVhat I claim is 1. A frictional clamping device comprising a resilientclamping member having at its ends arms inwardly turned at one side ofsaid member and spaced apart therefrom, and a second resilient clampingmember normally bearing between its ends against the first namedclamping member and having its ends respectively disposed between saidarms and the first named clamping member, the ends of said armsnormallybearing against the second clamping member intermediate of the endsthereof.
